When compiling with -fconcepts,
cp_parser_template_declaration_after_export calls
cp_parser_template_introduction and that preparses qualified-ids not
preceded by typename in such a way that, when we get to
cp_parser_parse_and_diagnose_invalid_type_name and then
cp_parser_diagnose_invalid_type_name, the nested name specifier no
longer carries the previous template-dependent context, so we don't
stand a chance to suggest the use of 'typename' any more.  Thus,
tolerate in the testcase the poorer error messages we get.

When an anon struct gets a name through a typedef, we reset its
linkage and that of its members.  Member functions may get vague
linkage, which schedules them for deferred output, but we don't want
to add them to the queue if they're uninstantiated templates,
e.g. because the enclosing function is a template.  They will be added
as needed when the enclosing template is instantiated.

The test in question fails for ilp32. The initial analysis I did in the PR for it
is that for ILP32 we generate somewhat different address forms that we'd need to adjust aarch64_classify_address to catch.
Given the optimisation this test checks for was added for GCC 8 it is not a regression, and improving the codegen on ILP32
would be an enhancement rather than a fix. So Richi has asked for it to be marked as XFAIL on ILP32, which is what this
patch does.
Checked that the test still passes on LP64 and appears as XFAIL on -mabi=ilp32.

	PR target/83009

This has been in my patch stack for quite some time. The problem here
was that we weren't handling arm_word_relocations in
arm_valid_symbolic_address and is the surest fix for this
for GCC8 and GCC7.

Regression tested on arm-none-linux-gnueabihf . Applying to
trunk and backporting to GCC-7 in a day or so.
